im getting the above error when i run this code snippet. Im trying to error proof user input by creating an error window when the user enters a value not in a dataframe. the code im running is below
import tkinter as tk
import tkinter.messagebox
import pandas as pd
root= tk.TK()
def customer_search():
try:
search = int(entry1.get())
except ValueError:
tk.messagebox("that customer doesnt exist, please enter a new number") #error proofing has to be added tomorrow
search = int(entry1.get())
k = df.loc[df['UniqueID'] == search]
k.to_excel("dashboard.xlsx")
df.to_excel("check.xlsx")
canvas1 = tk.Canvas(root, width=400, height=300)
canvas1.pack()
entry1 = tk.Entry(root)
canvas1.create_window(200, 140, window=entry1)
button1 = tk.Button(text='Enter a customer for analysis', command=customer_search)
button1.pack()
the error i get is as follows
Exception in Tkinter callback
Traceback (most recent call last):
File "C:/Users/....py", line 42, in customer_search

ValueError: invalid literal for int() with base 10: 'a'

tk.messagebox
is a module containing multiple dialogs, you probably want to use tk.messagebox.showerror("Info Title", "Info content")
.
Other dialogs are showwarning
and showinfo
, depending on your use case.
tk.messagebox
is a module not a function. A basic difference between modules and functions is that:
module()
. ( This is precisely the mistake you are making. ) function()
. ( This is what you should be doing instead. ) You need to do it this way (in customer_search
):
tk.messagebox.showerror("Title here", "that customer doesnt exist, please enter a new number")
where tk.messagebox.showerror
is a function in tk.messagebox
module .
